Hi, I've come here looking for information to help me integrate a solution using SAS HBA and disk backplanes (for my personal use), which may potentially come from different vendors. Of particular interest are:
Support for OpenBSD 5.9
Full function of RAID status LED's
Support for SES-2
I'm completely new to this area but after a bit of research there seems to be quite a variety of approaches followed by vendors over the last few years. I've seen some solutions which bypass the HBA>backplane, instead using a separate I2C connection. I've seen some other solutions where SGPIO is used, but on a separate header instead of as sideband connections on a SFF-8484. I've seen other solutions which adopt the standard physical connections for SGPIO (eg. via SFF-8484 or 8087), but which implement functionality on the backplane which seem to exceed that provided by IBPI (eg. HP Smartdrive), and which therefore presumably have implemented vendor-specific use permitted by SFF-8485.
I've not yet found much discussion of these issues or reliable information. So any pointers to outside resources or discussion or advice here would be very welcome.
